All Shrubs 20% Off and....

Yes, all shrubs are still 20% Off (hydrangeas, roses, evergreens, junipers, spireas, and more)but we've added limited quantities of some gorgeous specimens at 50% Off!

You'll have to stop in to see what John and Don have selected: for example, 10 of our 20 Admiration Barberries might be marked 50% Off, but the rest remain at 20% Off. Selections will vary from day to day as we thin the herd, so to speak, of some excellent "overstock" merchandise.

In stock merchandise only, no further discounts or adjustments to prior sales.

After more than 25 years of trialing plants, The Cincinnati Zoo & Botanical Garden knows which plants grow and look best in our region. By focusing that list to the plants that benefit pollinators the most, we have created the Zoo’s Best Plants for Pollinators Plant Series.  A selection of these can be found at Knollwood Garden Center, and a portion of the proceeds from every purchase will support further plant trialing at the Zoo.  Check out more information here, and look for this label at Knollwood!
